Welcome to my blog! I write about real-time communication, WebRTC, Chromium internals, bandwidth estimation, and related topics.

What to Expect

This blog will cover:

WebRTC — deep dives into the protocol stack, media pipeline, and browser implementation
Chromium — internals, debugging tips, and contribution notes
Bandwidth Estimation (BWE) — algorithms like GCC, BBR, and their behavior in real networks
GStreamer — pipelines, plugins, and integration with RTC systems
General systems programming — C++, networking, and performance

Code Example

Here’s a simple example of creating a PeerConnection:

Hey there! I’m Kaustav Ghosh — a software engineer who is trying to make your face look good over dodgy internet connection. If you’ve ever been on a video call that didn’t freeze at the worst possible moment, you’re welcome. (Okay, probably not because of me specifically, but I’m working on it.)

Currently, I’m at Microsoft, mostly focused on real-time video, network congestion control and video codecs — dedicated to the dark art of shipping video across the internet without suffocating the router — convincing pixels to trim the fat and bandwidth to cooperate. Before that, I built things at Tonbo Imaging — where we made thermal cameras cool (well, technically they detect heat, so… warm?) — and at Tata Consultancy Services. I also interned at Confirmtkt, where I learned that getting a confirmed train ticket in India is an extreme sport.
